Keep certain VM's running without array started

Hmm.. I‘m sorry I have only „tested“ this behaviour with the power outage I had. I did not stop the array with the GUI or anything. I thought the array is offline during a parity check which is definitely not right.

I forgot I had my array in „auto start“.

 

Nevertheless, it would be really a good idea to be able to run VMs from unassigned devices or cache drives with the array offline.

 

Sorry again = (

Allowing access to array members (cache included) while the array is stopped is probably not going to happen, for various reasons Tom has stated before.

 

However...

 

I see no real reason that we couldn't allow VM's that aren't on the array to operate. It's not like you couldn't set up a VM configuration where all the required elements were on a non array device, but it wouldn't be able to easily share those elements with the VM's currently configured. You would need a separate XML storage location, and an iso location for install media.

 

Maybe a GUI section for array limited VM's, and another for VM's on unassigned devices?

 

As soon as limetech actually takes control of UD instead of relying on dlandon to maintain it, I see no reason why we can't have 2 VM types. However, as long as limetech doesn't actively manage unassigned devices, it's probably not going to happen unless someone writes a plugin.

Unraid noob here, but it looks like this feature is something that I need as well.  Specifically, I have a Zerotier docker running that only uses the cache drive.  If I make a change on the server that requires stopping and starting the array then the docker shuts down and I lose access to the server.  I only have remote access to the server so this is a huge issue.

Unraid 6.8 supports WireGuard, which allows remote VPN access independent of the array status.

I'd also like to see the ability to start specific docker containers. If the data lives entirely on cache would be the condition to allow this. I.E. anything mapped to /mnt/user* would immediately disable this capability. 

 

I think RegEx could probably handle checking VM XML and Docker config for any reference to a non cache directory.

This world make using PFsense VMs a lot less chaotic when bringing down the array.

I would like this also.

My VM images are not on the cache disk, but on high speed unassigned devices drives, one step further from the array.
